Will getting fit rid me of my man boobs?

Q A FEW years ago, I developed gynaecomastia and it got me down. My GP ran testosterone tests and they came back a little low. He said surgery was the sole option, but would improving my health and fitness levels fix it?

A GYNAECOMASTIA, or breast enlargement in men, is very common. It is an increase in breast tissue, most often arising from a change in the ratio of the hormones oestrogen and testosterone.

Just as women produce small amounts of male hormones, such as testosterone, men have low levels of oestrogen (a mainly female hormone that in men helps, for example, with sperm production).

Gynaecomastia is so common that extra breast tissue, measuring up to 2cm across, is seen by many doctors as normal.

It appears often in men over 50, when hormone levels may alter. We also see physiological gynaecomastia in teenagers and babies. In these cases, the extra breast tissue goes within weeks (in babies), or a few years (in teenagers), as hormone levels settle.

Medication can also lead to the condition — including spironolactone (for high blood pressure), ketoconazole (for fungal infections) and cimetidine (used to suppress stomach acid). The reasons vary: some medicines act on hormones directly, others may affect the way the liver processes hormones; there is no single mechanism.

Another condition, called pseudogynaecomastia, or lipomastia, is an increase in breast fat within the tissue, rather than an increase in the tissue itself, and is associated with being overweight. If you have a high BMI, this may be to blame.

I’m unsure if you take medication, however you have had your testosterone levels measured and these were a little low. This may not be a complete explanation as to why you have the condition.

The growth of breast tissue is more to do with a change in the balance between oestrogen and testosterone, rather than absolute levels of the two hormones.

As to your question about diet and exercise, I can find no reliable evidence that this will help with gynaecomastia. However, for those with lipomastia, eating healthily and taking regular exercise to reduce your BMI to below 30 (the level of obesity), will resolve breast enlargement.

So I suggest you talk to your GP about confirming whether you have gynaecomastia or lipomastia — by an ultrasound scan if necessary. This would help you consider your next steps.

Surgery, normally only considered for cases that cause pain and psychological distress, costs about €6,000 privately and comes with the usual risks of an operation.

I hope there is a simple resolution for you.
